I don't consider myself a full socialisy, and I don't put a lot of thought into economics or politics, but I definitely lean towards socialism in a lot of ways. For me it was more thinking about things, and then hearing about socialism, and realizing that my thoughts on many things were very socialist. I also majored in French in college, and so studied France quite a bit. I can't say I have a full grasp on their political or economic situation, but I learned some things about socialism there.
I am a working-class schmoe, but socialism seems to be a good fit for society in a lot of ways. As other have said here, capitalism has its advantages, too, and is useful, but for the major things, like roads, schools, resources, keeping things among the people and not big business makes sense to me.
